Given that Farhan Akhtar's upcoming biopic is set in the mid-last century, a lot of elements used in the film were recreated to look the period.
However, the film's unit chanced upon a very old railway station 100 kilometers outside Delhi that looked perfect as a setting for the film.
According to sources, the abandoned railway station and colony at Rewari became the site of one of the biggest partition camps Shardara for the film.
A unit hand says, `The production team wanted to re- create the town of Shardara. Since the original location now has a completely modern look, an alternate location was being searched.
Then they discovered the old and forgotten spot at Rewari, which looks absolutely untouched. It evoked an authentic look from the bygone era.` Portions of Milkha Singh's growing up years at the Shardara refugee camp have been shot there.
